Comment:
This should use a separate user, there is no reason to run an irc bouncer as root.

```
system_accounts="_soju"
```

and `exec chpst -u _soju soju ...` in the run file.

I also switched the log and database directories, not sure if this would make sense:
```
make_dirs="/var/db/soju/ 750 _soju _soju
  /var/log/soju/ 750 _soju _soju"
```
And then chaning the default configuration to use those instead of `/var/lib/soju`.
